摘要
目的探讨后牙锁伴内倾型深覆有效、快速的治疗方法。方法对26例后牙锁伴内倾型深覆的患者进行模型分析,间隙开辟,根据锁的形成机制相应地设计支抗,利用小平导加垂直交互牵引进行治疗。矫治前后拍摄X线头颅侧位定位片进行分析和比较。结果 26例患者的锁及深覆均得到矫正。解除锁平均时间为3～6个月,前牙咬打开时间为3～5个月。结论根据错形成机制,注意颌内支抗,采取恰当的治疗措施。平导结合固定矫治器能使锁解除、前牙压低及后牙升高、建同步进行而缩短疗程。
Objective To investigate the treatment way of buccal crossbite with Angle Ⅱ^2 malocclusion. Methods 26 patients with buccal crossbite were treated by bite-plate and inter-arch mutual elastic after analyzing models and creating space. Cephalometric radiographes were measured and anasysised before and after treatment. Results All buccal crossbites and deepbites were corrected. Treatment time of unlocking buccal crossbites was 3-6 months on average; Treatment time of bite-opening means 3-5months. Conclusion Bite-plate with fixed appliance can intrude anterior teeth, raise posterior teeth, and create bite simultaneously. The period of treatment can be reduced.
